IMSI privacy protection method in 5G high-security terminal

Abstract

The invention discloses an IMSI privacy protection method in a 5G high-security terminal. An anonymization algorithm module and a privacy configuration module are additionally provided in the terminal, wherein the main function of the anonymization algorithm module is to perform anonymous processing on IMSI information, and the main function of the privacy configuration module is to selectively activate or close the anonymization algorithm module for application programs of different security levels. According to the IMSI privacy protection method provided by the invention, the privacy of theIMSI is ensured in the high-security terminal by using the anonymization algorithm so as to reduce the possibility of an attacker of capturing the IMSI information through the application programs ofthe terminal, so that the identity privacy of a user of the high-security terminal is protected. The application range of the method is wide, the method is not only suitable for the high-security terminals in the current 4G network, but also is suitable for the high-security terminals in the future 5G network. The requirements of identity privacy protection of users in the high-security industriescan be satisfied. The anonymization algorithm can also be extended to protect the identity information of other terminals.

Description

technical field [0001] The invention relates to a method for protecting IMSI privacy inside a 5G high-security terminal. Background technique [0002] Since 2015, ITU, 3GPP and other international telecommunication organizations have formulated requirements, standards and other schedules for 5G, and the world's leading telecom operators have also started to invest in 5G network trials in 2016. Operators plan to launch early 5G commercial services in 2018, and after three to four years of trials, they will realize 5G networks built with 5G standard technology proposed by 3GPP in 2021, and the world will officially enter the era of 5G services. [0003] 5G networks need to provide differentiated security services for different business scenarios, and be able to adapt to various network access methods and new network architectures. These new scenarios, new architectures, and new technologies all have higher privacy protection requirements for future 5G networks. Focusing on t...
